Application led September 8, 1914. Serial No. 860,553.

T0 all 'whom it may concern Be it known that I, HENRY F. SoHRoDER, citizenof then United States, residing at Windham, in the county of Fergus and State of Montana, have invented certain new and useful Improvements in Straw- Stackers; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it apper-l illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings, Figure 1 is a side elevation of the improved straw stacker attachment, mounted on a threshing machine, some parts being broken away, some of the exposed parts being shown in section, and some parts being indicated in different positions by means of dotted lines; Fig. 2 is a view, partly in plan and partly in section, taken on the line m2 m2 of Fig. 1, some parts being removed and some parts being broken away; Fig. 3 is a view, partly in plan and partly in section, taken 'on the line m3 x3 of Fig. 1, some parts being removed and some parts being broken away; Fig. 4 is a view, partly in end elevation and partly in section, taken on the line @c4 oi' Fig. 3; and Fig. 5 is a detail view, partly in plan and partly in section, taken on the line m5 m5 of Fig. l.

Of the parts of the threshing machine illustrated for the purpose of showing the improved stacker applied in working position, it is only necessary to note the machine case 1', supported on side sills 2, rear axle 3, rear wheels 4 and straw rack 5.

The parts above referred to may be of the standard or any desired construction.

The side sills 2 are rearwardly extended and rigidly connected by a pair of laterally spaced end sills 6, having bolted or otherwise rigidly secured to the intermediate p ortion thereof a casting 7, having a depending socket. 4A turntable 8, rectangular in form,

casting 7 for horizontal is supported on the n Rigidly secured to the swinging movement.

edge thereof, is rigidl intermediate portions of the side bars of the turntable 8 is a pair of laterally spaced bars 9, to the under side of which is bolted a casting 10, resting on the casting 7 and having a depending tubular trunnion 11, journaled in the socket -of said casting 7.

Journaled in the frontends of side board l extensions 12 on the turntable 8' is a horizontally extended driven .roller 13, and

Journaled inthe rear ends of said extensions isan idle roller 14. The ,rollers 13 and 1i are in parallel arrangement land a receiving or platform apron 15 runs thereover. delivery end of the machine case 1 and delivers the platform apron 15, substantially over the trunnion 11.

At the forward end of the turntable 8 is an upwardly and outwardly inclined ele- An open bottom hopper 16 closes the the straw from` the straw rack 5 onto vator frame 17, rigidly secured thereto for horizontal swinglng movement. On the outer face of each side board of the elevator frame l17, and at the lower -longitudinal 18 ysecured a guide rail is supported from the machine case 1 by a long rod l19, the inner end eled on a stud 20, secured to the top of said case. This stud 20 is axially alined with movement of the turntable 8.

YSlidably mounted on each guide rail 18 is a traveler 21, having the trunnions of a horizontal roller 22 journaled therein.l The trunnions of the roller 22 are both extended outward of the travelers 21 and have loosely journalcd on each thereof a large worm wheel 23. A horizontally extended delivery frame 24 issupported from the worm wheels 23 by castings 25, rigidly secured to the inner ends of the side boards of said delivery frame and to said worm wheels. By means of the travelers 21, the delivery frame 2l may be raised and lowered bodily and by means of the worm wheels 23 the outer. end of saidlfor lparallel movement toward and from the The upper end of the elevator frame 17 of which is swvthe trunnion 11 to permit free swinging 1:01161 22 is an ridle mner aafhavig as trunnions journaled in Abearings 28slidably mounted in slots 29, v'formed in the upper longitudinal portions of the side'boar s of the delivery frame 24, and which extend radially from the roller 22. An apron 30 travels over the rollers 26 and 27 an `the upper run of said apron travels over the roller 22, and the lower run thereof` travels over a relatively small idle roller 31, having its trunnions journaled in the travelers 21. The travel of the apron 30 between the rollers 26 and the two rollers 22 and 31 is in the same plane with the elevator frame 17, and the travel of said apron between the rollers 22rand31land the roller 27 is in the and 37 are journale'd in utershaft 41 by a runs over a sprocket wheel 45 on said coun- 'thus far described permit free,

with respect to the same plane with the delivery frame 24. Obviously, the slidingbearings 28 permit the upper end of the apron 30 to move toward and from the roller 22 to compensate for the varying length of the apron 36-between the rollers 22 and 26 during the raising and lowering movements of the delivery frame 24.

\ Vertically spaced above the apron 30 and `extending parallel therewith is a coperating apron 32 which runs over a lower driven roller 33 and an upper idle roller 34. The straw from the platform apron 15 is delivered between the aprons 30 and 32, which constitute an elevator, and is carried upward thereby and delivered onto a delivery apron 35. This apron 35 runs over anV inner driven roller 36 and an outer idle roller 37 ,i

that the rollers 36 the side boards of the delivery frame 24 in a plane below the delivery end of the apron 30 and that said delivery end overlaps the receiver end of the apron 35.

The above described aprons are driven by the following connections, 'to-wit: A transversely extended, horizontal shaft 38 is journaled in depending bearings on the sills 2 and 6 and has keyed to its outer end a pulley 39 over which runs a' belt, not, shown. This belt may be driven from any of the driven parts of the threshing machine. In the trunnion 11 is journaled a vertical shaft 40 and a countershaft 41 is extended parallel to the shaft 38 and journaled inbearings on the turntable 8. The shaft 40 is driven from the shaft 38 by a pair of intermeshing gears 42 and the shaft 41 is driven from the shaft 40 by a pair of intermeshin'g bevel gears 43. Obviously,the connections horizontal, oscillatory movements of the turntable 8 threshing machine. The are driven from the counsprocket chain- 44, which It is important to note rollers 13 and 26 tershaft, a sprocket wheel 46 on the roller 13, and a sprocket wheel 47 on the roller- By these connections, the apron 30 and -elers 21.

the apron 15 are driven in the direction of the arrows marked on Fig. 1. IThe roller 33- is driven by a cross belt 48, which runs over a-pulley 49 on the roller 26 and a pulley 59 on the roller 33. By this cross belt the apron 32 is driven in the direction of the arrow marked on Fig'. 1. A sprocket chain 51 runs over a-sprocket wheel 52 on the trunnion of the roller 22 and a sprocket wheel 53 on the trunnion of the roller 36, thus driving the delivery belt 35 in the direction ofthe arrow marked on Fig. 1.`

The travelers 21,'and hence the delivery apron 35, are raised lowing connections, to-wit: The lower ends of-.a pair of squareshafts 54 are journaled in castings 55,'secured'one to the-lower end of each of the side boards of the elevator frame 17 and also held therein against endwisemovement. 1 The upper ends of these shafts 54 are'jour'nale'd in bearings ongthe trav,-

rllhe shafts 54 are simultaneously rotated by a horizontal, transverse shaft 56, journaled in the sides of the turntable 8 and connected to said shafts by pairs of intermeshing bevel gears 57. yA hand crank 58 -is provided for rotating the shaft 56. Extending parallel to each shaft 54 is a screw rod 59, journaled at its lower end in a bearing formed in the respective casting 55 and lheld thereby ment. The upper end portions of these rods 59A have screw-threaded engagement with the respective travelersv 21. The screw rods 59 are rotated from the respective shafts 54 -by sprocket chains 60, which run over alined sprocket wheels 61 on screw ro the delivery end of the apron 30 is simultaneously shortened bythe raising of the travelers 21 and simultaneously lengthened by the lowering of said travelers, to compensate between the rollers 22 and 26, by a pair of screw rods 62. Theinner ends-of the screw the shafts 54 and 65 are driven from the respective shafts 54 by bevel pinions 66, slidably mounted on the respective rods 54 but held Vfor rotation therewlth. The bearings on the travelers 21, in which the upper ends of the shafts 54 are journaled, hold the bevel pinion 66 in mesh with the bevel gears 65.

60 o fthe machine case 65 zontal delivery'end portion,

maar@ is raised and lowered by oscillating the worm wheels 23 through the following connections, to-wit: Jdurnaled in the sides of the turntable 8 is a shaft 67 which extends parallel with the shaft 56 and is rotated by a hand crank 68. Extending parallel to each square shaft 54 is a square shaft 69, journaled at its lower en d in a bearing on the respective casting 55. The upper ends of 10 these shafts 69 are journaled in vertically spaced bearings 70, integrall formed with respective travelers 21. j Sli ably. mounted between each. pair of bearings 70 on the shaft 69 is a worm 71 which meshes with the respective worm wheels 23.

The shafts 69 are driven from the shafts 67 by intermeshing bevel gears 72.

. Guide strips 73 are extended between the rollers 33 and 34and support the upper and of the apron 32 for straight line travel.

Operation: The operation of the improved straw stacker may be brieiy stated as follows: As reviously stated, the straw is fliom the threshing machine into the hopper 16 and from thence deposited onto the platform apron 15. As shown, the hopper 16 terminates a comparativelyshort distance above the platform apron 15, thus 30 preventing the straw from being scattered by the wind. From the platform apron 15 the straw is delivered to the elevator and carried upward between the aprons and 32. vFrom a point above the roller 22 the 35 straw is carried outward from the machine von the horizontal extension of the apron 30. j From thence it is delivered onto the underlying delivery apron 35, carried outward thereby and deposited on the stack. By operating the crank 58, the delivery apron 35 may be raised as the stack increases in height. As the delivery apron 365 is raised, the delivery end thereof travels outward, owing to the inclination of the guides 18. To offset this outward travel of the apron 35, the

outerend thereof may be moved vertically by operating the crank 68 to oscillate the worm wheels 23 in a manner previously described. The importance of keeping. the de- 50 livery end of the apron 35 in substantially the same vertical plane is to build a stack `that is straight. By moving the turntable 8, the delivery end of the apron 35 may be swung in a semicircle to build a correspondlVhen the straw stacker is not in use, the delivery frame 24 may be raised vertically to its highest elevation and then swung into an inoperative position so that thefree end thereof rests on the top 1, as shown by dotted lmes in Fig. l.
